FEED MECHANISM FOR SAW-MILLS.

SPECIFICATION forming part of Letters Patent No. 355,071, dated December 28, 1886.

Application filed June 17, 1886. Serial No. 205,465. (No model.)

.To aZZ whom it may concern:

Be it known that we, GEORGE FRIOK and EDGAR PENNEY, citizens of the United States, residing at l/Vaynesborough, in the county of Franklin and State'of Pennsylvania, have invented certain new and useful Impro vementsin Feeding Mechanism for Saw-Mills; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the feed mechanism of that type of circular saw mills in which the power is derived from the saw arbor through friction-gearing.

Our improvement consists of certain com binations, each one of which is specified by a separate claim at the close of this specification.- Less than the whole number of these combinations may be used'; but the best results are obtained where all are used.

In order that our invention may be clearly understood, we have illustrated in the annexed drawings,and will proceed to describe,a practical form thereof.

Figure 1 represents a plan view of so much of a circular-saw mill as suffices to illustrate the application of our invention. Fig. 2 also represents a plan View, but where some parts shown in Fig. 1 are omitted, and others are broken away. Fig. 8 represents a longitudinal section in the plane indicated by broken line as m on Fig. 1. Fig. 4 represents a crossscction in the plane indicated by broken line y y on Fig. 1. Fig. 5 represents a cross-section in the plane indicated by broken line a e on Fig. 1.

The same letters of reference indicate identical parts in all the figures.

The feed-shaft 10 is driven from the frictionhub 2" of a duplex friction driving-pulley, 2, on the saw-arbor 1 to feed the carriage, and from the internal friction surface or ring, 2, of the rim of said pulley to gig the carriage back through the intervention of the friction-pinion 3 on one end of parallel shaft 4, friction-disk 5 on said shaft, friction-wheel 6 on cross-shaft 7 bevel-wheel 8 on said cross-shaft, and bevelwheel 9 on the feedshaft. Parallel shaft 4 is supported in bearings across a frame, 11, hinged at one end on feed-shaft 10, and so suspended at the other end that it can be turned to throw the friction-pinion 3 either out ofcontact or into contact with the friction-hub 2,

or with the internal friction-ring, 2. The hinged frame is suspended at one side by asuspension-link, 12, from a crank-pin, 13, of cranlcdisk 13 on rock-shaft 14. The canting strain put on parallel shaft 4 is compensated,

as regards the hinged frame, by suspending said frame at .its other side by a suspensionlink, 15, from one arm of a compensating lever, 16, a slot, 16*, in the other arm of which engages a crank-pin, 13, on crank-disk 13,diametrically opposite to crank-pin 18 and on the reverse outer side of said disk. The compensatinglever is fulcrumed on afixed bracketarm, 17.- The suspensiondink 15 consists of two rods connected by a nut, 15; with right and left threads, so that its length may be ac 7o curately adjusted.

Rock-shaft 14, supported in suitable fixed bearings, is provided, at the most convenient point for the operator, with a hand-lever, 18, which is cross-pivoted to the sleeve 18, by which it is secured to said shaft. By turning said lever crosswise of the rock-shaft thelatter can be rocked to turn crank-disk 13 for the purpose of raising or lowering the suspended end of the hinged frame, and throwing the frietionpinion in or out of gear. This handlever is cross-pivoted on its sleeve, in order that it may also be used for operating the shifter-rod 19, one end of which is connected by a link, 19, to said lever between broad cheeks 18 thereof, while the other end is connected with or engages a groove in the hub of friction-wheel 6. By turning the hand-lever on its C10SS-plVOl3-i. e.,lengthwise of the rockshaftthe friction-whee16 can be shifted along the face of the friction-disk 5,to change at will the speed imparted to said friction-wheel by said friction-disk. The friction-wheel is eonnected to its shaft by a groove and long spline, so that it may be slid, as required.

An adjustable collar, 7, is placed on crossshaft 7, to limit the shifting of the frictionwheel in one direction, it being limited in the other y direction either by the out-bearing 11 of parallel shaft 4, or by some other suitable means. Bearing 7 at one end of cross-shaft 7 is vertically pivoted at 11 between bracket- IOO arms 11 of hinged frame 11, and bearing 7 at the other end of said cross-shaft is horizon tally pivoted at 11 between cheeks 11 of the hinged frame, so that the said shaft may have suflicient lateral motion to throw friction-wheel 6 into firm contact with friction-disk 5, or out of contact. Bearing 7 has a lever-arm, 7 ,which projects up by the side of a vertical flange, 13, on crank-disk 13. Flange 13 has two setscrews, one, 18, above the center of the disk, and another, 18, below the center of the disk. These set-screws are so adjusted that either the one or the other presses against lever-arm 7 forcing friction-wheel 6 firmly against friction-disk 5 whenever friction-pinion 3 is driven; but when the friction-pinion is not running, then lever-arm 7 is relieved from both set-- screws, and the pressure between the friction-- wheel 6 and frietiondisk 5 suspended, so that indentation or flattening of the friction-surfaces is prevented. By means of these set screws the wear between friction-disk 5 and frictionwheel 6 can also be taken up.

We prefer to counterbalance the hinged frameand its appurtenances, as shown.

It will be observed that the single hand-lever 18-gives the operator complete control over the feed mechanism, not only for instant reversal, but also forinstant change of speed and simultaneous separation or relief of pressure between the several friction surfaces.

We claim as our invention.
